OSHA Issues Final Rule on Respiratory Protection
Revised Standard Adds A New Fit-Testing Protocol

WASHINGTON -- The Occupational Safety and Health Administration today announced an addition to the approved fit- testing protocol in its Respiratory Protection Standard. The revision adds a new quantitative fit-testing procedure to assist workers and employers in the proper fit and selection of respirators.

"Selecting the proper respirator is a vital step in protecting a user against potential over-exposures and adverse health effects," said OSHA Administrator John Henshaw. "The additional fit-testing protocol will help employers and employees to select the right respirator based on the conditions in their workplaces."

The new fit-testing protocol, referred to as the Controlled Negative Pressure (CNP) REDON protocol, requires three different test exercises followed by two redonnings of the respirator. The three test exercises, listed in order of administration, are normal breathing, bending over, and head shaking.

The procedures for administering the new CNP REDON protocol, with three test exercises and the two respirator donnings to an employee, and for measuring respirator leakage during each test, are summarized below:

Facing forward. In a normal standing position, without talking, breathe normally for 30 seconds; then, while facing forward, hold breath for 10 seconds during sampling.
Bending over. Bend at waist for 30 seconds and hold breath for 10 seconds during sampling.
Head shaking. Shake head back and forth vigorously several times while shouting for approximately three seconds and, while facing forward, hold breath for 10 seconds during sampling.
First redonning. Remove respirator, loosen all face-piece straps, and then redon the respirator mask; after redonning the mask, face forward and hold breath for 10 seconds during sampling
Second redonning. Remove respirator, loosen all face piece straps, and then redon the respirator mask again; after redonning the mask, face forward and hold breath for 10 seconds during sampling.

Complete details of the new respiratory protection fit-testing requirements and the notice of the final rule are published in today's Federal Register.

OSHA's role is to assure the safety and health of America's workers by setting and enforcing standards; providing training, outreach, and education; establishing partnerships; and encouraging continual improvement in workplace safety and health. For more information, visit www.osha.gov.
